what is polyethylene glycol used for

Polyethylene glycol (PEG) is a medication that is used to treat occasional constipation. It is in the laxative class of drugs and works by holding water in the stool to soften it and increase the number of bowel movements. PEG is available as a powder for solution and is usually taken once a day as needed for up to two weeks. It is also available in oral powder packets for single-use or in a bottle with a measuring cup. PEG is an over-the-counter medication, and as such, there is increased access to the drug. Healthcare providers need to emphasize directions for use and misuse. Patients should be counseled on the onset of action of medication as well as when to discontinue PEG.
